What is the second derivative on a graph?
What is the second derivative on a graph?
The second derivative is acceleration or how fast velocity changes. ? Graphically, the first derivative gives the slope of the graph at a point. The second derivative tells whether the curve is concave up or concave down at that point.
How do you find the second derivative of sin?
The derivative of sin(x) with respect to x is cos(x) . The derivative of cos(x) with respect to x is −sin(x) .
How do you differentiate sin and cos graphs?
The basic sine and cosine functions have a period of 2π. The function sin x is odd, so its graph is symmetric about the origin. The function cos x is even, so its graph is symmetric about the y-axis. The graph of a sinusoidal function has the same general shape as a sine or cosine function.
What is the second derivative of cosine?
The derivative of the cosine function is written as (cos x)’ = -sin x, that is, the derivative of cos x is -sin x….Derivative of Cos x.

What is the second derivative of Cos 2x?
Using the chain rule to find the derivative of cos(2x)
| cos2x | ► Derivative of cos2x = -2sin(2x) |
|---|---|
| cos 2 x | ► Derivative of cos 2 x = -2sin(2x) |
| cos 2x | ► Derivative of cos 2x = -2sin(2x) |
| cos (2x) | ► Derivative of cos (2x) = -2sin(2x) |
What is difference between sine and cosine wave?
A cosine wave and its corresponding sine wave have the same frequency, but the cosine wave leads the sine wave by 90 degrees of phase . In most practical situations, a lone cosine wave is the same as a lone sine wave; phase generally has meaning only when two or more waves having identical frequencies are compared.
What are second derivatives used for?
The second derivative of a function f can be used to determine the concavity of the graph of f. A function whose second derivative is positive will be concave up (also referred to as convex), meaning that the tangent line will lie below the graph of the function.
